Air Knocker vs Airsweep®

Air Knocker

AIRSWEEP®

Functionality

Air Knocker

  • Air Knockers induce vibration energy to the vessel wall, which transmits into the material to shake it loose

AIRSWEEP®

  • Directs smaller, equally powerful bursts of air along the bin wall, lifting material off the wall and back into the flow stream
  • Eliminates bridging, ratholing, or sticking problems
  • Stimulates up to a 2.44 m (8 foot) diameter circle of material around each nozzle

Noise Level

Air Knocker

  • Air Knockers can be extremely noisy

AIRSWEEP®

  • Makes a quick, ear-friendly “psst” or “pop”

Maintenance

Air Knocker

  • Metal and weld fatigue can occur due to vibration or hammering from piston air knocker. Wear and tear on vessel walls can be costly
  • Expensive to operate. Air Knockers use a lot of air or power to operate

AIRSWEEP®

  • No damage, vibration, stress or wear to vessel walls
  • Uses as little as 10 CFM of compressed air or gas
  • Only needs inspection every 6 months, and replacement of parts after 1,000,000 cycles
  • Longest industry warranty – 7 years

Material Control

Air Knocker

  • Sticky material remains, and builds up over time on bin walls, even if bridging is controlled
  • Periodic shutdowns may still be required to clean bin walls, especially if cross-contamination is an issue

AIRSWEEP®

  • Each pulse of the AirSweep sweeps along the bin walls, preventing material from adhering to the sides, or building up
  • In general, full clean out of the bin occurs with each batch, ensuring first-in/first-out material flow with no cross-contamination
